To all whomit may concern.'

Be it known that I, GEORGE Cousins, a citizen of theUnited States, and a resident of Oswe o, in the county of Oswego and State of ew York, have made certain new and useful Improvements in Spacer-Bolts,

of which the following is a specification.

My invention is an improvement in spacer bolts, and has for its object to provide a bolt-of thecharacter'specified, by means4 of which, walls, as for instance the Walls for concrete forms may be held in spaced relation by means of a single bolt, which(V engages both walls positively, and firmly holds I .15 the two walls from lateral movement toward or from each other, and so arranged that the bolt may be applied and removed,

in a minimum of time, and -with a minimum of labor.

In the drawings: Figure 1 is a transverse vertical section of a portion of a form,

showing the bolt in use, and with parts inj section; Fig-2 is a plan view of Fig. 1, and F ig. 3 is an end view of the clamping nut. f

The present embodiment of the invention is shown in connection with a form, comprising walls 1 and 2, arranged in parallel spaced relation, and the said walls 1 and 2; are supported by studding 3 and 4`respec- 1 tively. The studding 3 and 4: are secured to the respective walls by means of nails 5 or the like, and the said walls may be spaced: apart at any desired distance. The spacing mechanism comprises a bolt 6 of suitable 3.5 length, and having one of its ends pointed or bolt being in fact provided with a gimlet point, and the said point is adapted to 40 enter one wall of the form, and to enter the studding of the said Wall through a portion of its thiclmess.

It will be understood that the spacer bolts are arranged in spaced relation, throughout the length of the form, the spacing dependand threaded, as indicated at 7 The thread of the end 7 is a wood screw thread, the rod frusto-conical. At the small end of the sleeve, the said sleeve is externally threaded, as shown at 9, the threads being preferably of the same pitch as the threads of the gimlet point 7 The threads 9 extend from the 60 small end of the sleeve approximately half the length of the sleeve, and beyond the threads the said sleeve is slotted longitudinally, as shown at l0, the slots being at opposite sides of the sleeve. At the large end, the sleeve is laterally enlarged, to form clamping heads or jaws 11 and 12, the said heads being separated by the slots 10, before mentioned. Each of the said heads extends on opposite sides of the sleeve, and the adjacent corners of the heads at each end thereof are beveled, as indicated at 13. The heads are perforated transverse to the sleeve, at each end of the heads, and the ad- 'jacent perforations are in alinement, and 75 are adapted to receive carriage bolts 14, each of the said bolts being passed through the adjacent ends of the opposite heads and being engaged by nuts 15 to hold the bolts'in place.

In the use of the improved spacer bolt, the wall l is provided withl a transverse opening 16 at one of the studding B, the said opening extending through the studding, as shown in Fig. 1. The bolt or rod 6 is then 85 passed through the opening 16, and the gimlet pointed end is engaged with the opposite Wall 2, and with one of the studding connected therewith. The nut 8 is then engaged with thestudding 3 at the opening 90 16, and is threaded into the said studding a suiicient distance to prevent disengagement thereof, as indicated in Fig'l. After the nut has been engaged with the studding, the y walls are properly spaced, and the vnuts 15 :95` are then. tightened to clamp the heads or jaws 11 and 12 on the rod or bolt. The slots 10 permit the heads or jaws to move toward each other, and into gripping relation with respect to the rod or bolt, and it will be evident that when the nut 8 is clamped into place the walls 1 and 2 are properly spaced, and are rigidly connected with the spacing bolt, so that there is no possibility of either' wall moving toward or from the other. To .105 release the bolts, the nuts 15` are loosened, to permit the clamping jaws or heads to release the bolt orrod 6, after which the nut .nay be released from the wall 1, and the, bolt from the wall2. The heads may be eni 50 openings, the bolts being oppositely ar-l gaged by any suitable mechanism to turn the same, to cause the threaded end of the-I nut toengage the opening 16, and the bolt or rod 6 may be also turned by any suitable mechanism.. The device will hold the form walls 'at the required distance apart, and the said walls may be spaced at any distance desired, permitted by the length of the bolt or rod 6. l

It will be noted from the drawings, that the bolts 14 are oppositely arranged, so that the nuts 15 are on opposite sides of the nut 8. The threading 9 of the nut 8 is preferably of the same pitch as the pitch of the threads ofthe end 7 of the rod or bolt, but not necessarily s0. threads is the same, the nut and the gimlet pointed end of the rod or bolt may be simultaneously engaged with or disengaged from the walls.

With the improved spacer bolt, it is not necessary that the form walls beparallel, as the spacing bolts can be used with inclined walls, the said bolts engaging openings and holding the walls as firmly as when the walls are parallel.

I claim 1. In combination with the oppositely arranged walls, one of the Walls having an opening,l yof a spacer device comprising a bolt or rod adapted to pass through said of the said heads being beveled at each endopening, said bolt having a gimlet pointed end for engaging the opposite wall, a sleeve nut fitting the bolt or rod andl having a frustro-conical external surface, said sur` face being externally threaded at the small end for engaging the other wall, and the said small end being arranged adjacent to the gimlet pointed endl of the rod or bolt, said sleeve having oppositely arranged longitudinally extending slots at the opposite end to the screw threads, and the saidnut being enlarged laterally at the slotted end and at each side of the slots to form oppositely arranged gripping jaws or heads, each at the inner side thereof and having an opening at each end, the said openingsbe-y ing in alinement, bolts passing through the the gimlet pointed end of the rod or bolt,

When the pitch of the said sleeve having oppositely arrangedy longitudinally extending slots at the opposite end to the screw threads, and the said nut being enlarged laterally at the slotted end and at each side of the slots to form oppositely arranged gripping jaws or heads, and means for clamping the said heads on the rod orbolt. f

` 3. A device of the character specified, comprising a rod or bolt having one of its, ends gimlet pointed, a sleeve nut fitting the rod or bolt and having its external surface frusto-conical and arranged with the small end toward the gimlet pointed end .of the rod or bolt, said sleeve being externally 8 threaded at the smallend and having oppositely arranged longitudinally extending slots at the opposite end, said nut being enlarged laterally at the slotted end on each side of the slots to form gripping jaws or heads, said jaws or heads being beveled at each end on their inner faces, and having openings at each end, the said openings of the heads registering, bolts passing through the openings, the said bolts'being oppositely arranged, and nuts engaging the bolts for clamping the heads on the rod or bolt.
